It will he noted that the lower plate is so constructed that all working parts are housed between the plates 2 and 4.

ing wherein like characters designate correings 9 and 1() which are o1 me lfdulnji-- eating type. t

Loosely mounted on thesha'ft 8 is the female member 1.1 ot a *cone clutch which. ear- .ries a. small gear 12 which meshes with a large gear 13 keyed to n shaft 14 which is mounted in bearings 15 projecting upwardly from the plate ai. The mele member 16 of the cone clutch is slidably keyed to the shaft 8 and is moved into and out of engagexnent with the female ineieioer 11 by en operating' means, which @consists o the hori- Zonta] rod 17 journaled in bearings 18 prolectingg upwardly 'from the plate d and has its outer ends turned upwardly es at 19 to form 'convenient operating levers on each side of the machine. Springs 20 hold the levers 19 in toe position placed. The rod 'Pil is bent downwardly and across to form 'fs crank 21 which is connected to the hub 22 of the male member 1S ley e pin 23.

Mounted on efach end of heshaft 14 are cranks 26 which ere connected by links?? to vertical. reciprocating rods 28 whiclmfwori through bearings '2Q/'and tubes 30p-rejecting upwardly within'the tub l. The upper end of each tube.' 3() has e. self-lubricating bearing 31 andstalling box 3Q whicinare rigidly connected 'to'she wells of 'the cuis 1 by brackets B3. Une rod 28 is bii'urcsted as at'd and carries the header cross beam 35 on V@pivot pin 36. the other rod '28 has a gravity lsleli 37 pivoted at 38 to securely hold .the cross beam 35 in position. While the machine is in operation an inner or clot-hes-contain inpr tub or basket 39 rests on a ring 40, which has central cross pieces 41, and said ring 40 in turn rests ou prings 42 which in turn resi; on a plate i3 yplaced on the lic-team 44 oi: the outer tube 1. As will be noted the tub 39 has its side walls perforated as shown at l5 and it is plo-eed within :i ring d6 which is attached to 4ghe upper end of rods 47 which work in tuheslfl similar to the tubes 3G and lievinghearings i9 and 50 at their lower and upper ends.'

respectively and smiling boxes 51 above the bearings 50. A

The lower. ends of the rods 47 have the ends of a cable 52 attached thereto as indicated at, 53, said cable passing` over sheaves 54 andheingconnected at to a. foot lever 56 which is pivoted at 5T to a bracket 58 eX-i tending upwardly from the plate 4e.

By pressing downwardly onthe pedal 56 the rods 4K? end ring 216 are raised until the ring 4S comes into Contact with lugs 58 on the tulo 39 which in 'turn raises the inner tulo 39. This is done when the cross been@ 35 and eonnected parte have been swung upwardly into a vertical position around the nivor pin and heid in this position by perforstions d5.

misses passing e pin through the hole @Oi'ina har 61. (which is mounted in a housing and which can be raised in this, housing` by lift ing the knob G3) eudthe hole @el inatlug 65 carried by the cross har 35. This lifting of the tub 39 raises ity out of the Water in the tub 1 :ind allows the water in the elothes within the tub 39 to drain out through. the The clothes `can then be teiten from the tub and wiung through the wringer 66, which is carried on the upper end of a tube 6i whose lower end is onnected to a housing 38 in which is contained the gearing and clutches for loperanting the "wringer which will now ,he described.

llot-atabl y mounted on the shaft 8 Within the housing o8 are the female members 69 and of two cone clutches. lligidly eonnected to members 69 and Z0 are pinions? 1 and 7:2 which mesh with a pinion 73 keyed to e vertical shaft 74e which. extends upwsrdly within the tube 67. The male inemloers 75 and 7G of the clutches are slidably keyed to the shaft 8 es indicated et 77 and 78 and are held in spaced relationship to each other .by e yoke 79 which is slidahly mounted in brackets 80, rFhe yoke 79 is moved in either direction by a crank which has its horizontal erm 81 pivotally connected to the yoke as indicated at 82 and has its vertical arm extending upwardly 4from the housing 68 parallel to the tube 6? and i has handles 311 and 85 on its upper end exe tendini; to either side the mbe 67. As will readily loe seen, hy operating the handies-[8K2:` and 85 and yoke 79, the shaft 74.- Insy be kept at rest or caused to rotate in either direction by engaging the respective clutches.

Attached to the upper end of the vtube 6'? is'oiblock 86 having notches 87. said block 8o supporting the wringeicerrying bracket 88. An umn 89 shaped as shown, is pivoted at 90 between lugs 91 on the bracket 88 and has its lower end Q2 inserted through a hole 93 into one of the notches S7. A spring J4 tends to keep the arm 89 in this position. This arm will lock the wringer in any desired position there are about 12 notches 87 in i the block 86.

Keyed to the upper end of the shaft M is a beveled geez which meshes with a gear 96 on a shaft 97 which operates the lower roller 98 of the wringer A. gear 99 on. the shaft 97 meshes with a gear ,100 on the shaft of the. upper wringer roll 101.

lotatably mounted in the header cross beam 35 is an internally threaded bushing 102 into which is screwed a shaft 103 said' shaft heine; locled in the bushing 102 by a lock nut 10e. l

Rigidly connected to the lower end. of the she'ftfll, is e cup header plate 1.05 which carried s series of suction cups 106. The

cups '106 have necks 107 which extend one end of an arm 116 and a pawl 117. A

miese@ throu h openings 108 in the header 105 and are he d therein by a cap 109 which has open ings 110. The necks 107 are bored outas at 111 and have a check valve 112 resting on a seat 113 in the upper end of the neck.

Formed on the upper end of the bushing 102 is a ratchet wheel 1111 which has a cover.

115 and to which .cover is pivotally connected and then downwardly and outwardly as at 122- and carries a roller 123 which is adapted to engage with an inclined lug 124 on the in side of the tub 1 on the u stroke of therods 28 and the header cross am 35. A small rod 125 fextends rearwardly from the part 122 and through a, bracket 126 carried on the side of the cross beam 35. A spring 127 is coiled around the rod 125 between the bracket 126 and the partl 122.

As the roller 123 engages the inclined lug 124 on the upward 'stroke of the rods 28 the bar 119vis moved along the header-35 and in turn moves tlle'arrtii 116 which rotates 'the cups 106.

cover 115 and-consequently'the ratchetcwheel 114 as the pawl 117 is inengagement within 'thej teeth of" the ratchet 114. As the ratchet l1airsi rotated the bushing 102 will be rotated and consequently the shaft 103` which is rigidly locked in it and-the cup header 105 which is rigidly fastened to the lower end of the shaft 103. On the downward stroke of the rods 28 and header 35 the roller 123 will leave the inclined surface 124 and the spring 12T will force the bar 119 in theopposite direction which in turn will bring the pawl 117 back and into engagement with one of the succeeding teeth of the ratchet wheel 114.

As will readily be seen the shaft 103 and cup header 105 and cups 106 carried thereby will he slightly rotated at every upward movement of the rods 28 and header cross beam 35.

The rods 28 will be moved up and downL hrougfh the action of the cranks 2G and links 2T when the shaft 14 is rotated. 130. 131 and 132 indicate depressions in the plate L1 to receive the cranks 20. wheel 7 and gears 13 and l2. Deprcssions to receive the lower ends of the rods 4T are indicated at 135.

Figs. 10 and 11 illustrate a different type of cup which may be used in place of the rl`his cup consists of a conical member 140 which has a cylindrical neck 141 into which fits a hollow cylinder 142. hastened to the upper end of the cylindrical neck 141 and extending through slots 143 in the cylinder 142 are two cross bars 1'4/1 placed at right angles to each other. yAbove the.

cross bars is a disk 145 upon which is placed the lower end of a sprin 146, the upper end being held by a cap 14g which is threaded onto the upper end of the cylinder 142. The cylinder 142 is screwed into oy l nings inthe cup header 105 and the cap 111 alsoacts las a lock nut.

bottom of thecylinder 1412, and be heidi-by a screw 151.

In operation, the beam 35, and the suction cups connected thereto, are swung up out ofthe tub 39, and the clothes are placed lin the tub, and the beam and cups swung down to originalpositionj- When the machine is started the rotation of the shaft lll, by means of the connecting rods 28, causes an up and down motion of the suction cups, and the tub 3 94 will yield tos; 'certain extent in consequence of the springs This-action has the effect ot pumping the water through the clothes, and the clothes arc compressed at each operation. Asvthe cups lift suction through the clothes is induced and the cups fil1` with water which is discharged on the next down stroke and escapes through the openingse in the tub 9 and A fibre washer 150vmay'be pliicedonxthe flows downwardly to the bottom of the outerl tub and alg-ain circulates through the clothes. At each stroke the gang of cups is rotated slightly to apply the same to a new portion of the clot-hes. The screw 103 permitsvan adjustment to vary the amount of pressure applied to the clothes, or to accommodate different quantities of clothes. The machine may be run at any speed desired7 and it has been foundV that as high as seventy-dye strokes per minute-may be successively used1 giving a multiplicity of operations `which will speedily clean the clot-hes. After they are cleaned, the whole inner 'basket or tub may be lifted by pressing onfthe treadle 56, and the clothes then passed from the basket to the wringer and wrung. out in the ordinary way, the wringer being driven by the same power as the washer.
